Shapley 1 is a small and moderately bright planetary nebula in Ara. It was not an easy object in an 8" telescope, but could be clearly seen. In a 12" telescope it is an easy object appearing as a small ring, similar to the Ring Nebula, but fainter and much more circular with a strong response to an OIII filter.
